As another example, if the food material name of a certain custom food material contains two characters, such as "apple", the designated area is equally divided into two drawing areas according to the preset layout rule, for example, a left area for drawing "apple" and a right area for drawing "fruit", and the drawing position of each character is determined as the center position of the corresponding drawing area, and the size (such as the character size) of the character is determined as the size corresponding to the length of the drawing area according to the preset layout rule. For example, a food material icon drawn according to "apple" may be as shown in fig. 7.

For another example, if the food material name of a certain custom food material contains three characters, such as "kimchi", the designated area is equally divided into four drawing areas according to a preset layout rule, for example, the designated area is divided into "tian" font, each drawing area is allocated in the order from left to right and then from top to bottom, for example, the upper left area is used for drawing "spicy", the upper right area is used for drawing "white", and the lower left area is used for drawing "dishes", the drawing position of each character is determined as the center position of the corresponding drawing area, and the size (such as the character size) of the character is determined as the size corresponding to the length of the drawing area according to the preset layout rule. For example, the food material icon drawn according to "kimchi" may be as shown in fig. 8.

It should be noted that, when the name of the food material is drawn, the related parameters such as the font, the font color, and the like can be set and adjusted according to the requirement, and the embodiment of the application is not limited.

As can be seen from fig. 6 to 8, the food material icons corresponding to different custom food materials have different display effects, and a user can directly identify and distinguish the custom food materials through the food material icons, so that the user experience is improved.

In some embodiments, the food material information includes a food material name and a food material category, and the food material icon generated according to the food material name includes two layers, namely, the first layer for drawing the food material name and the second layer located at the lower layer of the first layer. According to the different food material types, the second image layers are drawn to different colors, so that the food material icons of different types of customized food materials have different ground colors, and therefore, a user can recognize and distinguish different customized food materials according to the food material icons and can distinguish the types of the food materials according to the ground colors of the food material icons.

As one possible implementation, a controller of a refrigerator is configured to: drawing a food material name in an appointed area in the first map layer, wherein the appointed area is an area corresponding to a display area of a food material icon, and the layout of characters contained in the food material name in the appointed area accords with a preset layout rule; acquiring target RGB values corresponding to food material categories, wherein different food material categories correspond to different RGB values; and drawing the color of the designated area in the second layer according to the target RGB value, wherein the second layer is arranged at the lower layer of the first layer. The corresponding relationship between the food material category and the RGB value may be established in advance.

As another possible implementation, the controller of the refrigerator is configured to: drawing a food material name in a first designated area in a first layer, wherein the first designated area is an area corresponding to a display area of a food material icon in the first layer, and the layout of characters contained in the food material name in the first designated area accords with a preset layout rule; and acquiring a target RGB value corresponding to the food material category, and drawing the color of a second specified area in a second layer according to the target RGB value, wherein the second specified area is an area completely overlapped with the display area of the food material icon in the second layer, and the second layer is arranged at the lower layer of the first layer. The second designated area is overlapped with the display area of the food material icon, that is, in the same preset coordinate system, the coordinate point set forming the second designated area and the coordinate point set forming the display area of the food material icon are the same coordinate point set.

Fig. 9 exemplarily shows a schematic diagram of a food material control generated according to "kimchi", and fig. 10 exemplarily shows a schematic diagram of a food material control generated according to "beef tripe". As can be seen from fig. 9 and 10, since the "kimchi" and the "tripe" belong to different food material categories, the food material icon of the "kimchi" and the food material icon of the "tripe" have different ground colors.

As can be seen from the above embodiments, the refrigerator has a controller that generates a food material management interface according to food material information corresponding to each food material in a storage chamber, and displays the food material management interface on a display, where the food material management interface includes a food material control generated according to the food material information corresponding to each food material, and the food material control includes a food material icon and a food material name, where when there is a preset icon material corresponding to the food material name, the food material icon is generated according to the preset icon material, and when there is no preset icon material corresponding to the food material name, the food material icon is generated according to the food material name. Because the food material names of different custom food materials are different, the food material icons generated according to the food material names are different inevitably, and therefore, even if a plurality of food material controls corresponding to the custom food materials exist in the food material management interface, a user can also directly identify and distinguish the custom food materials through the food material icons, and the user experience is improved.

According to the above embodiments, the application further provides a method for displaying a food material management interface, which is applied to a refrigerator, and an execution main body of the method includes but is not limited to a controller of the refrigerator. Fig. 11 is a flowchart illustrating the method according to an exemplary embodiment, and as shown in fig. 11, the method may include:

step 111, obtaining food material information corresponding to each food material in the storage room, wherein the food material information at least comprises a food material name.

Step 112, displaying the food material management interface according to the food material information corresponding to each food material, wherein the food material management interface comprises food material icons generated according to the food material information corresponding to each food material, the food material icons are generated according to preset icon materials when preset icon materials corresponding to the food material names exist, and the food material icons are generated according to the food material names when preset icon materials corresponding to the food material names do not exist.

In some embodiments, when there is no preset icon material corresponding to the food material name, generating the food material icon according to the food material name includes: and drawing the food material name in a specified area in the first map layer, wherein the specified area is an area corresponding to the display area of the food material icon, and the layout of characters contained in the food material name in the specified area accords with a preset layout rule.

In specific implementation, the information of a display area of a food material icon is obtained, and an appointed area in a first layer is determined; determining layout information of the food material name in the designated area according to the designated area and the number of characters contained in the food material name, wherein the layout information comprises the size of each character and the position of each character in the designated area; according to the layout information of the food material name in the designated area, drawing each character in the food material name in the designated area of the first map layer.

In some embodiments, the food material information further comprises a food material category; when the preset icon material corresponding to the food material name does not exist, the food material icon is generated according to the food material name, and the method further comprises the following steps: acquiring target RGB values corresponding to food material categories, wherein different food material categories correspond to different RGB values; and drawing the color of the designated area in a second layer according to the target RGB value, wherein the second layer is arranged at the lower layer of the first layer.

In some embodiments, the user interface for presenting food materials is referred to as a food material management interface. In the food material management interface, the food materials in the refrigerator are displayed in the form of food material controls to the greatest extent, one food material corresponds to one food material control in the food material management interface, and each food material control at least comprises a food material name and a food material icon, wherein the food material icons can be generated according to the pictographic picture of the food material and can also be generated according to a self-defined generation algorithm of the food material name.

In some embodiments, after the user puts the food material into the refrigerator, the user inputs the shelf life and the food material putting time (or the food material production date) by operating the user interface, and the controller receives the food material putting time or the food material production date input by the user and stores the food material putting time or the food material production date in the food material information in the local data. In other embodiments, the controller is configured to: detecting opening and closing signals of the box doors, when all the box doors are detected to be closed, indicating an RFID detection module connected with the box doors to identify RFID tags in all storage rooms so as to acquire identification information of each RFID tag to obtain an information set, determining a target RFID tag placed in the storage room by the operation by comparing the newly acquired information set with a locally stored information set, recording the food material placing time of food materials corresponding to the target RFID tag according to the current time, and updating the locally stored information set according to the target RFID tag and the recorded food material placing time.

In some embodiments, the food material information in the local data includes a food material shelf life and a food material put-in time, from which the freshness of the food material can be monitored, such as a remaining shelf life, an expiration time, and the like of the food material. In order to remind the user of the freshness degree of each food material, the freshness identifier of the food material can be displayed in the food material management interface, and if the freshness identifier of the food material is loaded in the corresponding food material control for display, the freshness degree of the food material is reminded for the user.

In some embodiments, the freshness identifier of the food material may specifically be a progress bar representing the freshness degree of the food material; in other embodiments, the freshness indicator of the food material may be a text indicator directly indicating the remaining shelf life of the food material. In the embodiments, the food materials are indiscriminately displayed in the form of progress bars or character marks, so that it is not very convenient for a user to directly distinguish which food materials are overdue, which food materials are about to be overdue, which food materials are relatively fresh, and the like, and the user experience is not friendly enough.

In some embodiments, the controller of the refrigerator is configured to: the method comprises the steps of obtaining food material information corresponding to each food material in a storage chamber from local data, generating a food material management interface according to the food material information corresponding to each food material, wherein the food material management interface comprises a food material control corresponding to each food material, displaying a food material icon and a freshness identification of the food material in the food material control, generating the food material icon according to a preset food material icon material corresponding to a food material name, and also generating a custom icon according to the food material name, wherein the freshness identification of the food material is used for indicating the freshness of the food material, the freshness identification of the food material is generated into different states according to different freshness of the food material, the freshness of the food material can be determined according to the input time and the quality guarantee period of the food material, and the input time and the quality guarantee period of the food material are contained in the food material information.

In the above embodiments, the freshness degree of the food material may be quantitatively characterized by the remaining shelf life and/or the freshness ratio of the food material. The remaining quality guarantee period of the food material can be calculated according to the quality guarantee period of the food material, the food material putting time and the current time, specifically, the remaining quality guarantee period of the food material = the quality guarantee period of the food material- (the current time-the food material putting time), and when the remaining quality guarantee period of the food material is less than 0, the food material is overdue; the ratio of the fresh ratio of the food materials, namely the ratio of the residual quality guarantee period of the food materials to the quality guarantee period of the food materials is less than or equal to 100%, and the longer the residual quality guarantee period of the food materials is, the closer the fresh ratio of the food materials is to 100%, which means that the food materials are fresher.

In addition, the production time of a factory-type food such as milk or yogurt can be stored as the time for putting in the food. According to different specific food materials, the food material placing time mentioned in the embodiment of the present application includes, but is not limited to, the food material generating time or the time when the user places the food material into the refrigerator for the first time.

In some embodiments, when the remaining shelf life of the food material is less than zero, generating the freshness indication into a first state to alert the user that the food material has expired using the freshness indication of the first state; when the freshness ratio is not less than the preset value, the freshness identification is generated to be in a second state, so that the freshness identification in the second state is used for reminding a user that the food material is relatively fresh; and when the freshness ratio is smaller than the preset value, generating the freshness identification into a third state so as to remind the user that the food material is about to expire by using the freshness identification in the third state.

It should be noted that the preset value may be set by a user according to a requirement, for example, set to 33%.

Compared with a scheme of indiscriminately displaying the optional freshness of the food materials in a progress bar or character identification mode, the freshness identification of the food materials is generated to be in different states when the freshness of the food materials is different, so that a user can more intuitively distinguish which food materials are expired, which food materials are about to expire, which food materials are fresh and the like, and the user can more conveniently and quickly acquire information which the user wants to pay attention to, for example, the user can quickly find the expired food materials according to the freshness identification in the first state, or quickly find the food materials which are about to expire according to the freshness identification in the third state and the like.

In some embodiments, the freshness indicator of the first state is a first picture indicator floating on the food material icon, and the first picture indicator covers the food material icon. The first picture identifier may display a symbol or a text indicating that the food material is expired, such as "expired". As a possible implementation manner, when the remaining shelf life is less than zero, a first picture identifier is generated in a first preset area of a first layer above the food material icon, and the first preset area overlaps with a display area of the food material icon, so that the food material icon is partially covered by the first picture identifier. As a possible implementation manner, the transparency of the first icon identifier is greater than 0% so that the food material icon can be displayed through the first picture identifier.

Fig. 12 is a freshness indicator of a first state, specifically an exemplary first picture indicator, shown in the present application according to an exemplary embodiment. As shown in fig. 12, an expired text prompt is displayed in the first picture identifier 1201, the first picture identifier 1201 floats on the food material icon 1202 to be displayed, the food material icon 1202 is partially covered, and the covered portion of the food material icon 1202 can still be displayed through the first picture identifier 1201 because the transparency of the first picture identifier 1201 is greater than 0%, so that the first picture identifier is sufficiently striking, a user can notice the expired food material quickly, and the user is not influenced to identify the food material through the food material icon.

In some embodiments, the freshness indication of the second state is a second progress indication displayed in a second preset area. Specifically, when the fresh proportion is not smaller than the preset value, a second progress mark is generated in a second preset area of the second layer. The second preset area is an area which does not overlap with the display area of the food material icon, such as a gap area between the food material icon and the food material name.

In some embodiments, the second progress indicator may specifically be a progress bar including a progress region and a background region, a length of the progress region represents a progress value, the progress value corresponds to a freshness ratio, and the progress region and the background region are filled with different colors to realize explicit distinction of the two regions. As a possible implementation manner, the progress area of the second progress indicator is configured to be different colors according to the difference of the numerical value range in which the freshness ratio falls. For example, when the fresh proportion of the food material is higher than the first value, the progress area of the second progress mark is configured to be green, and when the fresh proportion of the food material is lower than the first value, the progress area of the second progress mark is configured to be yellow. The first value is greater than 0 and less than the preset value, for example, the first value is preset to 66%, when the fresh proportion e of the food material is (33%, 66%), the progress area of the second progress mark is configured to be yellow, and when the fresh proportion e of the food material is (66%, 100%), the progress area of the second progress mark is configured to be green.

Therefore, the user can judge the freshness of the food materials according to the length of the progress area and can judge the freshness of the food materials according to the color of the progress area, the user can quickly notice the fresh food materials (for example, the progress area of the progress bar shows green food materials), and the user can notice the less fresh food materials (for example, the progress area of the progress bar shows yellow food materials).

Fig. 13 is a freshness indicator of a second state, specifically an exemplary second progress indicator, according to an exemplary embodiment of the present application. As shown in fig. 13, a second progress indicator 1301 displays a gap region between a food material name 1302 and a food material icon 1303, the second progress indicator 1301 does not overlap with the food material name 1302 and the food material icon 1303, the second progress indicator 1301 includes a progress region and a background region, and the progress region and the background region are filled with different colors.

Fig. 14 is a freshness indicator of another second state, specifically another exemplary second progress indicator, shown according to an exemplary embodiment of the present application. Unlike the second progress marker shown in fig. 13, the progress value of the second progress marker shown in fig. 14 and the freshness ratio of the food material characterized by the progress value are different from those of fig. 13, and the progress area of the second progress marker shown in fig. 14 is filled with a different color from that of fig. 13. As can be seen from the embodiments shown in fig. 14 and 13, when the freshness indicators shown in fig. 14 and 13 coexist in the food material management interface, a user can quickly find out a fresher or less fresher food material according to the color of the progress area of the freshness indicator; when two identical food material icons (namely, two identical food materials, such as a broccoli put in first and a broccoli put in later) are displayed in the food material management interface, a user can quickly compare the food materials which are fresher according to the colors of the progress areas of the freshness identifiers corresponding to the two food material icons.

It should be noted that, a plurality of numerical ranges, such as 30% -40%, 40% -50%, and the like, may be preset as required, one numerical range corresponds to one color, and when the second progress indicator is generated, the progress area of the second progress indicator is drawn into the corresponding color according to the numerical range in which the fresh proportion of the food material falls.

In some embodiments, the freshness indicator of the third status comprises a third progress indicator and a third text indicator displayed in a third preset area. Specifically, when the freshness ratio of the food material is smaller than the preset value, a third progress mark and a third character mark are generated in a third preset area, where the third preset area may be an area in a third layer, and the third preset area is not overlapped with a display area of the food material icon, such as a gap area between the food material icon and the food material name.

Similar to the second progress marker, the third progress marker may specifically be a progress bar including a progress region and a background region, the length of the progress region represents a progress value, the progress value corresponds to a fresh proportion, and the progress region and the background region are filled with different colors to realize explicit distinction of the two regions. As a possible implementation manner, the progress area of the third progress indicator is configured to be different colors according to the difference of the numerical value range in which the freshness ratio falls. For example, when the freshness ratio of the food material is higher than the second value, the progress area of the third progress marker is configured to be orange, and when the freshness ratio of the food material is lower than the second value, the progress area of the third progress marker is configured to be red.

In some embodiments, the third progress marker can be different in width from the second progress marker to enable an explicit distinction between the freshness identification of the second state and the freshness identification of the third state.

In some embodiments, the third text label is used for indicating the remaining shelf life of the food material, and in order to save the interface display area occupied by the freshness label and make the freshness label in the third state more intuitive and conspicuous, the third text label may be displayed floating on the background area of the third progress label, so that the third text label does not need to occupy the display area outside the area where the third progress label is located. Specifically, a third progress mark is generated in a third preset area, and a third text mark is generated in an area corresponding to a background area of the third progress mark in an upper layer of the third progress mark.

Fig. 15 is a freshness indicator of a third status according to an exemplary embodiment of the present application, which is specifically an exemplary third progress indicator and a third text indicator. As shown in fig. 15, a third progress mark 1501 shows a gap region between a food material name 1502 and a food material icon 1503, the third progress mark 1501 does not overlap with the food material name 1502 and the food material icon 1503, and the third progress mark 1501 includes a progress region and a background region, and the progress region and the background region are filled with different colors. As can be seen from fig. 15 and 13, the third progress mark has a wider width than the second progress mark. As shown in fig. 15, the third text label 1504 is displayed in the background area of the third progress label, and the third text label 1504 is specifically a text prompt like "2 days left", and "2 days left" is the remaining shelf life of the food material.

In some embodiments, the controller is configured to: acquiring food material information corresponding to each food material in the storage room from the local data, wherein the food material information comprises food material names, food material shelf lives and food material putting time; acquiring corresponding preset food material icon materials, such as pictographic files of food materials, from the local data according to the food material names, generating food material icons in a zeroth layer according to the preset food material icon materials, and determining the remaining quality guarantee period of the food materials according to the current time, the quality guarantee period of the food materials and the food material putting time; when the remaining shelf life of the food material is less than zero, generating a first picture identifier for indicating that the food material is out of date in a first preset area in a first layer to generate a freshness identifier in a first state, wherein the first layer is a layer above a zeroth layer, and the first preset area is an area overlapped with a display area of an icon of the food material; when the remaining quality guarantee period of the food materials is larger than zero, calculating the fresh proportion of the food materials according to the remaining quality guarantee period of the food materials, and when the fresh proportion of the food materials is not smaller than a preset value, generating a second progress mark in a second preset area in a second layer to generate a freshness mark in a second state, wherein the second preset area is an area which is not overlapped with a display area of an icon of the food materials in the second layer, and the progress value of the second progress mark corresponds to the fresh proportion of the food materials; when the fresh proportion of the food materials is smaller than a preset value, a third progress mark and a third character mark are generated in a third preset area in a third layer to generate a freshness mark in a third state, the third preset area is an area which is not overlapped with a display area of the food material icon in the third layer, the progress value of the third progress mark corresponds to the fresh proportion of the food materials, and the third character mark is used for indicating the remaining shelf life of the food materials. In some embodiments, the first layer, the second layer, and the third layer may be the same layer or different layers.

In some embodiments, the food material information in the local data is periodically acquired, and the food material management interface is updated according to the acquired food material information, so that the freshness identifier in the food material management interface is updated in time.

In some embodiments, when it is detected that an RFID tag is newly added or reduced in the refrigerator, the food material information in the local data is updated according to a change condition of the RFID tag.

In some embodiments, after detecting that the food material information in the local data is updated, the updated food material information is acquired, and the food material management interface is updated according to the updated food material information, so that the freshness identifier in the food material management interface is updated in time.

According to the embodiment, the freshness of the food materials is monitored according to the food material placing time and the food material shelf life in the food material information, the freshness identification used for indicating the freshness of the food materials is generated in the corresponding food material control in the food material management interface to be displayed so as to remind a user of the freshness of each food material, and the freshness identification of the food materials is generated into different states when the freshness of the food materials is different, so that the food materials which are overdue, about to be fresh and the like can be distinguished more intuitively by the user, and the information which the user wants to pay attention to can be obtained more conveniently, for example, the user can quickly find the overdue food materials according to the freshness identification in the first state, or quickly find the overdue food materials according to the freshness identification in the third state and the like.

Based on the above embodiments, the present application further provides a method for indicating freshness of food in a refrigerator, which is applied to the refrigerator, and the execution subject of the method includes but is not limited to a controller of the refrigerator. Fig. 16 is a flowchart illustrating the method according to an exemplary embodiment, and as shown in fig. 16, the method may include:

step 1601, obtaining food material information corresponding to each food material in the refrigerator, wherein the food material information comprises food material putting time and food material quality guarantee period, and the food material putting time and the food material quality guarantee period are used for determining freshness of the food material.

Step 1602, generating a food material management interface according to the food material information corresponding to each food material, where the food material management interface includes a food material control corresponding to each food material, the food material control includes a food material icon and a freshness identifier, where the freshness identifiers are generated into different states when the freshness degrees of the food materials are different.

In some embodiments, the degree of freshness of the food material comprises a remaining shelf life determined from a current time and the food material insertion time, the food material shelf life, and/or a freshness ratio, the freshness ratio being a ratio of the remaining shelf life to the food material shelf life; generating a freshness indicator for a first state when the remaining shelf life is less than zero; when the freshness proportion is not less than a preset value, generating a freshness identification in a second state; and when the freshness proportion is smaller than a preset value, generating a freshness identification in a third state.

In some embodiments, generating a freshness identification of a first state when the remaining shelf life is less than zero comprises: generating a first picture identifier in a first preset area, wherein the first preset area is an area which is in a top layer of the food material icon and is overlapped with a display area of the food material icon, the first picture identifier partially covers the food material icon, and the first picture identifier is used for indicating that the food material is overdue.

In addition, the progress area of the third progress mark is configured to be different colors according to the difference of the data range in which the freshness ratio falls. In addition, the third text mark is positioned on the upper layer of the background area of the third progress mark.

Step 1603, displaying the food material management interface on a display screen of the refrigerator.

Fig. 17 is a user interface according to an exemplary embodiment, which is specifically an exemplary food material management interface. Referring to fig. 17, the food material management interface is divided into two display areas, left and right; the left area comprises an RFID tag identification control and food material display areas corresponding to food material categories, such as fruits and vegetables, wherein food material icons and food material names of the corresponding categories are displayed in each food material display area; the right area comprises recommended menu controls and food material display areas corresponding to the storage chambers, such as a refrigerating chamber, a temperature changing chamber, a freezing chamber and the like, and corresponding food material icons and food material names are displayed in each food material display area. In addition, the right area of the food material management interface shown in fig. 17 further includes a custom area, and the custom area is used for displaying new food materials which are not classified by the user in the refrigerator. In the food material management interface shown in fig. 17, the number of food materials identified by the RFID tag in the refrigerator is displayed.

When the food material management interface shown in fig. 17 is displayed on the display screen, the user can click the custom area to trigger the partition classification operation flow of the food material in the custom area.

Illustratively, in response to the user clicking on the custom area, a virtual storage interface as shown in fig. 18 is displayed, in which the food material information to be stored in the partition and the storage room options that can be allocated, and related function controls such as "determine", "cancel", and the like are displayed. And the user realizes the partition storage of the food materials in the user-defined area by operating the control in the virtual storage interface.

According to the embodiment, partition management of the food materials can be achieved, but a user needs to operate each newly added food material in the refrigerator one by one, the intelligent management degree of the refrigerator on the food materials is low, and the user experience is poor.

Embodiments that can further improve the intelligent management capability of the refrigerator and improve the user experience will be described in detail below.

In some embodiments, the local data includes identification information of a plurality of RFID tags and corresponding food material information, and the RFID tags are classified into a first type RFID tag and a second type RFID tag according to whether each RFID tag is currently placed in the storage room or moved out of the storage room, wherein the first type RFID tag refers to an RFID tag currently placed in the storage room, and the second type RFID tag refers to an RFID tag currently moved out of the storage room.

In some embodiments, whether the RFID tag is the first type RFID tag or the second type RFID tag is determined according to the third attribute value of the RFID tag, that is, the third attribute value of the first type RFID tag is different from that of the second type RFID tag. Illustratively, the third attribute value of the first type of RFID tag is 0, and the third attribute value of the second type of RFID tag is 1.

It should be noted that the third attribute value is used to distinguish the first type RFID tag from the second type RFID tag, and the specific form of the third attribute value is not limited in the present application, and may be different status marks possessed by the first type RFID tag and the second type RFID tag, for example, the marked status of the first type RFID tag is a storage status, and the marked status of the second type RFID tag is a removal status, or different storage paths corresponding to the first type RFID tag and the second type RFID tag, for example, the identification information of the first type RFID tag is stored in the first table, the identification information of the second type RFID tag is stored in the second table, and so on.

In addition, each RFID tag has a first attribute value that characterizes a repository with which the RFID tag was previously associated. For example, if the first attribute value =0 of a certain RFID tag indicates that the certain RFID tag has been associated with the refrigerating compartment in advance, and if the first attribute value =1 of the certain RFID tag indicates that the certain RFID tag has been associated with the freezing compartment in advance … …, when the user uses the RFID tag to identify food, the user should select the corresponding RFID tag according to the storage compartment into which the food should be put, for example, because "apple" should be put into the refrigerating compartment, the user should select the RFID tag associated with the refrigerating compartment in advance to identify "apple". It should be noted that to facilitate the user in distinguishing the storage compartments to which each RFID tag is associated, the RFID tags associated with different storage compartments may be artificially produced in different colors, for example, a red RFID tag may be used as the RFID tag associated with the refrigerator compartment, a green RFID tag may be used as the RFID tag associated with the freezer compartment, and so on.

Based on this, the controller of the refrigerator is configured to: food material information corresponding to the first type of RFID tags is obtained from local data, and a first information set is obtained; and then displaying a food material management interface according to the first information set, wherein the food material management interface comprises food material display areas with the number equivalent to that of the storage chambers, food material controls generated according to the food material information are displayed in each food material display area, and the food material controls corresponding to the RFID tags with the same first attribute values are displayed in the same food material display area.

In specific implementation, the controller may determine the first type of RFID tags according to the third attribute values of all locally stored RFID tags; and acquiring food material information corresponding to the first type of RFID labels according to the identification information of the first type of RFID labels to obtain a first information set.

In the above embodiment, since the first attribute value of the RFID tag represents the storage room to which the RFID tag is associated, the food material controls corresponding to the RFID tags having the same first attribute value are displayed in the same food material display area, and the food material controls corresponding to the RFID tags having different first attribute values are displayed in different food material display areas, that is, the food material controls of the food material in the same storage room are displayed in the same food material display area, so that an automatic food material partitioning process is realized, and a user does not need to operate each newly added food material in the refrigerator one by one, thereby improving the intelligent management degree of the refrigerator on the food material, and improving the user experience.

Fig. 19 is a food material management interface according to an exemplary illustration of the present application, and as shown in fig. 19, the food material management interface includes three food material display areas, namely, a food material display area corresponding to a refrigerating chamber, a food material display area corresponding to a wide-temperature chamber, and a food material display area corresponding to a cold-temperature chamber, where each food material display area displays a food material control corresponding to a food material in a corresponding storage chamber.

In some embodiments, the first attribute value of the RFID tag may be an attribute value stored in local data corresponding to the identification information of the RFID tag, and the first attribute value of the RFID tag may be obtained according to the identification information of the RFID tag.

In other embodiments, the first attribute value of the RFID tag is specifically a code segment of a tag code of the RFID tag, and the tag code of the RFID tag may be identified by the RFID detection module, and the code segment written with the first attribute value is analyzed according to a composition rule of the tag code, so as to obtain the first attribute value of the RFID tag.

For example, assuming that the 25 th bit of the 28-bit tag code is used to write the first attribute value of the RFID tag, the first attribute value of the RFID tag is "4" according to the tag code "012345678220123456782201234567".

Based on this, the controller of the refrigerator is further configured to: for each acquired first type RFID tag, acquiring a tag code of the first type RFID tag from local data; intercepting a first code segment used for writing a first attribute value of a first type of RFID label from a label code to obtain the first attribute value of the first type of RFID label; determining a target storeroom associated with the first type of RFID label according to the first attribute value; determining a target food material display area corresponding to the target storage room; and drawing the food material control corresponding to the first type of RFID label in the target food material display area.

In some embodiments, each food material control comprises an explicit tag identification in addition to the food material icon, the food material name, and the freshness identification, so as to prompt a user which food material controls correspond to food materials identified by the RFID tag.

In some embodiments, the dominant tag identifications of the food material controls in the same food material display area are drawn to be the same color, and the dominant tag identifications of the food material controls in different food material display areas are drawn to be different colors. Therefore, the user can judge the storage room where the food material is located according to the color of the dominant label mark.

Fig. 20 is a schematic view of a food material control according to an exemplary embodiment shown in the present application, and as shown in fig. 20, the food material control includes a food material icon 2101, a food material name 2102, a freshness identification 2103, and an explicit label identification 2104. Fig. 21 is a schematic view of another food material control shown in an exemplary embodiment of the present application, and different from the food material control shown in fig. 20, colors of the dominant tag in fig. 20 are different from colors of the dominant tag in fig. 21.

As previously mentioned, to facilitate the user in distinguishing the repository with which each RFID tag is associated, the RFID tag entities associated with different repositories may be artificially produced or labeled with different colors. Based on this, in some embodiments, the dominant label identifier of the RFID label is drawn to the same color as the color of the label entity, the dominant label identifier of the food material control in the same food material display area is drawn to the same color, and the dominant label identifiers of the food material controls in different food material display areas are drawn to different colors, so that the user can select the RFID label associated with the designated storage room to identify the food material in the designated storage room according to the color of the dominant label identifier of the food material control in the food material display area corresponding to the designated storage room.

In some embodiments, each RFID tag further has a second attribute value, where the second attribute value is pre-corresponding to the color value and is used to represent a color of the dominant tag corresponding to the dominant tag identifier, that is, the dominant tag identifiers of the food controls corresponding to the RFID tags having the same second attribute value are rendered in the same color, and the dominant tag identifiers of the food controls corresponding to the RFID tags having different second attribute values are rendered in different colors. For example, according to the pre-established correspondence relationship between the second attribute value and the color value, if the second attribute value =0 of a certain RFID tag, the color of the dominant tag identifier representing the RFID tag should be drawn as red, if the second attribute value =1 of the RFID tag, the color of the dominant tag identifier representing the RFID tag should be drawn as green, and so on.

In some embodiments, the second attribute value represents the refrigerating chamber, the first attribute value represents the freezing chamber, and the second attribute value represents the temperature-changing chamber, so that in the displayed food material management interface, the dominant tag identifier of the food material control in the food material display area corresponding to the refrigerating chamber is displayed in the first color, the dominant tag identifier of the food material control in the food material display area corresponding to the freezing chamber is displayed in the second color, and the dominant tag identifier of the food material control in the food material display area corresponding to the temperature-changing chamber is displayed in the third color.

In some embodiments, the second attribute value of the RFID tag may be an attribute value stored in the local data corresponding to the identification information of the RFID tag, and the second attribute value of the RFID tag may be obtained according to the identification information of the RFID tag.

In other embodiments, the second attribute value of the RFID tag is specifically a code segment of a tag code of the RFID tag, and the tag code of the RFID tag may be identified by the RFID detection module, and the code segment written with the second attribute value is analyzed according to a composition rule of the tag code, so as to obtain the second attribute value of the RFID tag.

For example, assuming that the 26 th bit of the 28-bit tag code is used to write the second attribute value of the RFID tag, the second attribute value of the RFID tag is "5" according to the tag code "012345678220123456782201234567".

Based on this, the controller of the refrigerator is further configured to: for each first-class RFID label, intercepting a second code segment used for writing a second attribute value of the first-class RFID label from the label code of the first-class RFID label to obtain the second attribute value of the first-class RFID label; determining a target color value corresponding to a second attribute value according to the second attribute value; and when the food material control corresponding to the first type of RFID label is generated according to the food material information corresponding to the first type of RFID label, drawing the dominant label identification of the food material control according to the target color value.

In some embodiments, the controller of the refrigerator is further configured to: detecting opening and closing signals of the doors through a detector connected with the detector, and when all the doors are detected to be closed (for example, when the closing signals of the doors are detected, judging whether all the doors are closed according to the recorded state of each door, if all the doors are closed, determining that all the doors are detected to be closed), acquiring a zeroth information set, wherein the zeroth information set comprises identification information of all RFID tags in the storage room which is identified most recently; determining the latest removed RFID label by comparing the zeroth information set with the first information set; and modifying the third attribute value of the latest removed RFID label to mark the latest removed RFID label as a second type RFID label, wherein the second type RFID label is the RFID label which is currently removed from the storeroom.
